exterior angle theorem
A) 83°
B) 68°
C) 97°
D)62°

Answer:
A: 83°
Step-by-step explanation:
The exterior angle theorem states that the sum of the two interior angles of a triangle is equal to the exterior angle of that same triangle.
In this case, the two opposite interior angles to the exterior angle are: 52° and 31°.
Sum of them = 52 + 31 = 83°
